“…The genetic improvement of economically important traits especially growth traits is the prerequisite for profitable goat farming. Growth traits are the cardinal factors and should be appraised in order to ameliorate economic stability of meat industry (Magotra et al., 2021). The cost of rearing can be dwindled by enhancing growth rate during the early period, which directly enhance farmer's economy.…”

Globally, India stands second in goat population, with the total of 148.88 million goat (Livestock Census, 2019). Beetal is one of the prime goat breeds of India with total population of 0.71 million (Gowane et al., 2020). Beetal is a large-sized breed, distinguished by its black and white, sometimes red mottled and black mottled coat colour. It is a highly prolific and heat tolerant goat breed mainly reared for meat and milk production. The genetic improvement of economically important traits especially growth traits is the prerequisite for profitable goat farming. Growth traits are the cardinal factors and should be appraised in order to ameliorate economic stability of meat industry (Magotra et al., 2021). The cost of rearing can be dwindled by enhancing growth rate during the early period, which directly enhance farmer's economy. Genetic basis of traits is very essential for evolutionary response (a gradual change

“…Given the large differences between breed sizes in sheep and goats (ranging from an adult pygmy goat weighing 25-30 kg to adult Tyrolean mountain sheep weighing 100-130 kg), liveweight for all animals was also estimated using the Brody growth curve dependent on sheep or goat breed standards. [14][15][16] The breed and sex of the patient were taken from the clinical records. The breed-specific liveweight of adult animals was taken, where possible, from the book 'The colour atlas of domestic livestock breeds (Farbatlas Nutztierrassen)'.…”

“…After data cleaning and final preparation, a total of 5113 antibiotic doses administered remained in the dataset (Figure 1). As a large number of actual liveweights were missing from this dataset (2881/5113; 56.3%), the standardised liveweight for each sheep or goat breed was calculated for all animals in this study using the Brody growth curve [14][15][16] and used to calculate the total mg/kg of antibiotic administered.…”

BackgroundMonitoring antibiotic use is essential to provide a framework enabling veterinarians to use antibiotics prudently.MethodsElectronic medical records from the University of Veterinary Medicine's Clinic for Ruminants in Vienna were analysed with respect to sheep and goat antibiotic doses administered over a 15‐year period (2005–2019). Antibiotic use was assessed using total milligrams per kilogram (mg/kg), total milligrams, number of doses administered, defined daily doses (DDD) for cattle and estimated DDD for sheep.ResultsA total of 5113 antibiotic doses were recorded over the 15‐year period. Urinary tract disorders required the highest number of doses administered per animal (mean 16.9; median 16.0). Antibiotic use patterns varied according to the metrics used for analysis. By mg/kg, the largest proportion of antibiotics administered were penicillin/streptomycin (43.0% of the total mg/kg), followed by tetracyclines (17.3%) and sulphonamide/trimethoprim combinations (15.2%). By number of doses administered, the most frequently used antibiotics were penicillins (excluding combinations with streptomycin) (33.9% of total number of doses administered), fluoroquinolones (25.1%), third/fourth‐generation cephalosporins (13.6%) and penicillin/streptomycin (13.4%).LimitationsAs the university clinic was a city‐based referral centre, this analysis cannot be compared directly with antibiotic use in commercial herds or flocks.ConclusionsThe considered choice of antibiotic use metrics is essential for an effective and meaningful analysis of the responsible use of antibiotics by veterinarians in practice.

“…Üç farklı modelin canlı ağırlık ve zaman arasındaki korelasyon katsayıları cinsiyetlerde ve doğum tiplerinde R:0,89 olarak tespit edilmiştir. Beetal keçisi oğlaklarından 12 aylık ağırlıkları alarak yapmış oldukları çalışmalarında, belirtme katsayısı (R 2 ) %99 olarak tespit etmişler ve büyümeyi en iyi tanımlayan modelin Brody olduğunu bildirmişlerdir (13). Benzer bir çalışmada, Sirahi keçilerinin 12 aylık ağırlıkları kullanarak 5 farklı model uygulamışlar ve Brody modelinin en iyi model olduğu, (R 2 : %99.1) bildirmişlerdir (14).…”

Bu çalışma, Diyarbakır İli Bismil İlçesinde entansif yetiştiricilik yapan bir süt keçisi işletmesinde mevcut 30 baş erkek ve 30 baş dişi toplam 60 baş Halep keçisi oğlakları kullanılmıştır. Çalışmada, oğlaklara ait doğum ağırlığı ve 7 aylık canlı ağırlıklar ölçülmüş ve bu ağırlıklara ait büyüme eğrisi modellerinden Linear, Gompertz ve Richards büyüme eğrisi modelleri denenmiştir. Kullanılan modeller içerisinden en iyi modelin tespit edilebilmesi için belirtme katsayısı (R2) ve hata kareler ortalaması (HKO) istatistiki değerleri kullanılmış olup, büyümeyi en iyi açıklayan modelin; tekiz doğan (0.98±2.66), ikiz doğan (0.97±1.33) ve dişi Halep keçisi oğlaklarında (0.98±1.31), Richards büyüme eğrisi modeli en iyi tanımlarken, erkek Halep keçisi oğlaklarında ise denenen modellerin tümü sırasıyla 0.975±1.76; 0.976±2.01; 0.976±2.49 bulunmuş olup, Gompertz ve Richards modelleri aynı ölçüde tanımlamasına rağmen, HKO en küçük olan Gompertz modelin büyümeyi tanımlayan en iyi model olarak tespit edilmiştir. Sonuç olarak kullanılan büyüme modellerinin araştırma materyalimiz olan Halep Keçisi oğlakları ile iyi bir uyum sağladığını, yapılması düşünülen erken seleksiyon ile oldukça isabetli sonuçların elde edilebileceği kanısına varılmıştır. Çünkü tespit edilen belirtme katsayıları ( R2) son derece yüksek olmasına karşın, bunlara ait hata kareler ortalamaları (HKO) da o ölçüde küçük tespit edilmiştir.
